EMINENT DOMAIN - The right of the government, both state and federal, to take private property for a necessary public use, with just compensation paid to the owner. Through eminent domain, the state may acquire land (either fee, leasehold, or easement) for streets, parks, public buildings, public rights-of-way, and the like. The state may delegate the power of eminent domain to local governments and to public corporations and associations such as school districts.

A description which fails to enclose an area by returning to the point of beginning is defective.
